Purpose: Bilingual children often demonstrate a high rate of disfluencies, which might impact the diagnostic evaluation of fluency disorders; however, research on the rates and types of disfluencies in bilinguals' two languages is limited. The purpose of this research is to profile disfluencies of two types, stuttering-like disfluencies (SLDs) and…

There is a pressing need in Iran for the translation of widely used speech-language assessment tools into Persian. This study reports the interjudge and intrajudge reliability of a Persian translation of the Stuttering Severity Instrument-3 (SSI-3) (Riley, 1994). There was greater than 80% interjudge and intrajudge agreement on scale scores for…

This article analysed the acoustic structure of voiced stop ++ vowel sequences in a group of persons who stutter (PWS). This phonetic unit was chosen because successful production is highly dependent on the differential tweaking of right-to-left anticipatory coarticulation as a function of stop place. Thus, essential elements of both speech motor…

This exploratory study investigated sensory-motor mechanisms in five people who stutter (PWS) and five people who do not (PNS). Lip kinematic and coordination data were recorded as they produced bi-syllabic nonwords at two rates (normal and fast) in three conditions (jaw-free, immediately after insertion of a bite-block, and after a 10-min…

This study examined interjudge agreement levels for five adult listeners assessing either overt stuttering or disfluency types in the spontaneous speech of eight young children. Results showed that the interjudge reliability for judgments based on a disfluency taxonomy was not significantly different from that based on stuttering. The importance…

This study examined intrajudge and interjudge agreement for the Lidcombe Behavioral Data Language (LBDL), a behaviorally based stuttering taxonomy. Ten experienced speech language pathologists and 10 undergraduates applied the LBDL to stuttered speech on two occasions. Intrajudge agreement was high for both groups, but only the experienced judges…

Seventy-nine children (ages 3 through 7) were asked to discriminate between the speech (fluent and disfluent) of two puppets, identify the one who "speaks like you," and evaluate their speech. Children from age 3 showed evidence of some awareness of disfluencies but most children reached full awareness at 5. Negative evaluation of…

Listeners compared 10 individuals' suitability of speech at three stages of treatment for stuttering (before, immediately after, and six months after) with 10 non-stutterers. Ten speaking situations with different demands were rated using a newly developed instrument. Results indicated the instrument can be scored reliably and the factor…

A panel of speech professionals was randomly presented with speech samples from four neurogenic and four developmental stutterers and was asked to classify them accordingly without any patient knowledge. Results support the view that, based on the patient's verbal output only, it is difficult to distinguish between neurogenic and developmental…

Research and clinical data regarding concomitant speech and language problems in children who stutter are reviewed, along with theoretical models explaining this interrelationship. A framework is presented for the differential evaluation of children who stutter, involving four areas of assessment: case history, fluency assessment, language skills…
